Army MARS TANGO net
The TANGO net is an informal net. This net occurs in the afternoon allowing many stations to check in during their drive home (from work). Purpose of this net is to check out your equipment and get to know other stations. From an AF MARS point of view, procedures are different on this net. Typically one gives station callsign only at the begining of transmission and only the netcontrol station callsign at the end of transmission.
